“…The SF/HA hydrogel exhibited the similar mechanical properties and biocompatibility as the natural tissues. Lin Wang et al 53 used laccase to cross-link tyramine-modified hyaluronic acid (mHA) with silk fibroin so as to achieve the silk fibroin hydrogel with high structural stability and optimal formability. The proposed route represents a new method for constructing the flexible double network hydrogels using enzymes.…”

“…Silk fibroin (SF) is composed of a heavy chain (~390 kDa) and a light chain (~26 kDa); the heavy chain contains 5.3% of tyrosine (tyr) [235], making SF a suitable candidate to form hydrogels mediated by laccase. Such SF hydrogels present low elastic modulus, but the simultaneous conjugation of SF with hyaluronic acid-tyramine resulted in increased toughness and flexibility [236]. The increase in elasticity can be due to extra hydrogen bonds and van der Waals forces, and decrease of ÎČ-sheet conformation in the SF chains [237].…”

“…For example, it can catalyze substrates to form phenol radicals, which participate in hydrogel fabrication. 98,99 However, since the polymers used in hydrogel fabrication are too large and have high redox potential for laccase, substrates are too large to enter the active sites and make laccase difficult to be used as a cross-linking enzyme. 100 …”
